ironhide 1.0.0 released

[skeet70]

We rewrote our open source tool to encrypt and decrypt files to users and groups, ironhide, in Rust and released it as 1.0.0. Specific nodejs versions and npm install are no longer required. For now it can be installed with cargo install ironhide, but releases to more package managers will be coming soon. If you have a package manager request, let us know!
